This is a replacement turn signal flasher module. It will eliminate fast turn signal blinking, known as hyperblinking, that occurs when you replace your turn signal bulbs with LEDs. It has been designed specifically for use with LEDs.

This module is specifically for your vehicle! It will be 100% plug and play. Just remove the factory flasher, and plug this one in.


Why do you need this module? When your factory turn signal bulbs go out, your vehicle's flasher senses that less power is being used, and it will blink the turn signals quickly to alert you. When LED turn signal bulbs are installed, it lowers the load on the circuit too, because LEDs use less power. You get the fast blinking, known as "hyperblinking," even though the LEDs are functioning just fine. Basically, your car thinks the bulbs went out!

To slow down the blinking to regular speed, you can add resistors to increase the circuit's power consumption again. However, whenever possible, replacing the flasher with a module like this is the easiest option. This is the unit that actually controls the blinking speed, and makes the "clicking" noise.

  1. Fixes hyperflash but adds more issues Review by Omi

    - Fixed hyperflash
    - First signal/click is delayed then then normal rate clicking
    - Clock and passenger side "airbag is off" light will click along with turn signal.
    - Opposite side of tail lights will randomly click when the signal is on at the opposite side. So when I turn on right signal, the left tail light will click as well (and it's the actual taillight that clicks not the signal part). This happens sporadically.

    DD has offered to send me replacement flasher i will test it out and update my review. (Posted on 10/12/16)

  2. Fixes hyperblinking, introduces long first blink Review by Jim

    Similar review as Isolato ... The unit is well built and does what it says it will do - the hyperblinking is gone.

    However - the first flash of the signals after you hit the signal is noticeably longer than stock. Takes a bit of getting used to...

    Minor annoyance on an otherwise solid product. (Posted on 8/19/16)

  3. Works good. Could be better. Review by Isolato

    First things first. This flasher relay does what it is supposed to do: it fixes hyperblinking associated with LED flasher bulbs, and it works with any combination of incandescent and LED bulbs. The unit is solidly built, and is offered at a very competitive price.

    Here are my nit-pics, that I'd love to see Diode Dynamics address. The relay clicking is louder than stock, and the first "blink" of the blinking sequence is much longer than the rest. To each his own, but I personally find both of these aspects annoying.

    Lastly, I'd love it if Diode Dynamics offered a "tap turn" relay that allowed the driver to flash 3-blinks automatically by just tapping the turn signal (as offered on most cars these days). (Posted on 8/14/16)

  4. Needed of course! Review by Samson

    Better than a resistor! Not hard to install although it was hard for me to find the port. (Posted on 2/15/16)

  5. Easy hyperblink fix Review by William

    Easy to install and installs in under a minute. It works with LED and stock bulbs. Doesn't matter what turn signals you use it will always blink at the same rate. (Posted on 7/7/15)

  6. You need it. It works. Get it. Review by Zaneman

    This thing works and installs in under a minute. End of story. Wait there is more..It works with LED and stock bulbs. I had it installed with rear LED bulbs and stock fronts and there was no issue. If you want the look of beautiful LED blinkers then you need this. (Posted on 12/16/14)

  7. It Works Review by Nick

    Easy to install, and its works. hides under the dash nicely! Highly recommended. (Posted on 11/26/14)

  8. Better than resistors Review by Alex C.

    Bought these to go along with the LED front turn signals. Definitely get these rather than tinker with the wiring and resistors. It took me some time to pull the stock flasher out under the steering column but it wasn't too bad. There is a noticeable initial delay if you look closely but I didn't mind it as there is no more hyper blinking! (Posted on 9/13/14)

  9. Essential Buy IMO Review by MikeBRZ

    I watched many YouTube videos on soldering resistors and such into the wiring when upgrading to LED turn signals in the BRZ. I was really hesitant to do that because I have no expertise in that kind of handiwork. Then I found this, and it was the most valuable purchase for me when it came to upgrading my turn signals. Easy installation, but it helps if you have someone nearby with really small hands to install it. Love this flasher because it prevents me from potentially screwing up the exterior lighting in my car! Definitely would recommend this product. (Posted on 6/16/14)

  10. Fixes hyperflash and no initial signal delay Review by Los

    Bought this when the flasher that came with my new tail lights had an initial delay when signaling. DD's works how it should. (Posted on 5/30/14)

  11. Easy hyper flash fix Review by Tristaneasy firtu stab

    Got this along with my switchback led turn signals for my FRS. Works perfectly. Blinks at stock rate. Doesn't matter what turn signals you use. Oem or led it will always blink at the same rate because it's digitally limited. Super easy install. (Posted on 5/29/14)
